Abstract
The invention discloses a manual winding structure of a curtain. The manual winding structure comprises a driving wheel, a digging rope for driving the driving wheel to rotate and a fixing bracket for arranging the driving wheel; a connection rod is connected with the fixing bracket; and the manual winding structure is characterized in that: a driven wheel is arranged at the lower end of the connection rod, and the digging rope without a bead is wound on the driving wheel and the driven wheel. As the digging rope is not provided with the bead, impact is avoided in the contact between the digging rope and a roller during pulling of the digging rope, no sound is ensured and the mute aim is fulfilled; and as the phenomenon of clamping the bead is avoided, the curtain can be rolled more easily and flexibly.
Description
Technical field
The present invention relates to a kind of curtain manual coiling structure.
Background technology
Current hand-operated curtain winding-structure, is all with a kind of rope sheave with pearl, is commonly called as pelletron.Pull moving pelletron, pelletron drives the rotation of active winding wheel, reaches the object of rolling or fall curtain; The larger noise of collision generation due to pearl in pelletron and roller, does not feel well people, when especially having a rest in office space or needing peace and quiet, does not feel well especially suitable; The Chinese patent that is 200810062760.X as the patent No. discloses a kind of curtain manual coiling structure, comprise roller, chain rope, fixed mount, on described chain rope interval be fixed with can with roller on the chain pearl of groove transmission engagement, its spy is being to be also connected with on described fixed mount a brake bar straight down, is provided with and can enters but the snap ring that do not allow chain pearl to pass for chain wire clips on brake bar; Owing to using the stay cord of pearl chain, sometimes when pulling pelletron, there will be stuck phenomenon, also due to a variety of causes, make pearl loosening in stay cord, rope slippage causes two pearls to contact, thereby cannot pull, prior reason is to adopt band pearl pelletron, in drawing process, can send " chuckleing " noise, affect people's rest work, require further improvement design.
Summary of the invention
Technical problem to be solved by this invention there is no noise, uses the more curtain manual coiling structure of easy and flexible while being to provide a kind of coiling.
The present invention solves the problems of the technologies described above adopted technical scheme: a kind of curtain manual coiling structure, comprise driving wheel and for driving stay cord that driving wheel rotates and for the fixed mount of driving wheel is installed, it is characterized in that: on fixed mount, be also connected with to lower connecting rod, in the lower end of connecting rod, one follower is installed, has a stay cord without pearl to be wrapped on driving wheel and follower.
As improvement, the coiling obtuse angle profile of tooth that described driving wheel is distributed with a plurality of coiling acute angle profiles of tooth that are used for rolling and is used for discharging on tangent circumference, and the coiling acute angle profile of tooth number that is used for rolling is more than the coiling obtuse angle profile of tooth number that is used for discharging.
As improvement, the middle part of described fixed mount has an installation shaft, and described driving wheel is installed in rotation in described installation shaft by bearing, and in the front portion of described installation shaft, adopt jump ring by driving wheel axial limiting in this installation shaft.
Improve again, be lined with the first iron cover between described installation shaft and bearing, between installation shaft and driving wheel, be provided with back-moving spring.
Further improve, be also arranged with pad in described installation shaft, this pad is between jump ring and driving wheel.
As improvement, described fixed mount includes fixedly iron plate and mounting seat, described installation shaft is located in mounting seat, and in installation shaft, there is a perforation, described connecting rod is located in mounting seat, fixedly the middle part of iron plate has the cutting that can insert described perforation, and fixedly the horizontal part of iron plate has installing hole.
Further improve, described connecting rod is by head rod, the second connecting rod, the 3rd connecting rod is connected in sequence, one end of head rod is fixed in mounting seat, the other end of head rod has through hole, there is screw to pass the mounting hole of one end on through hole on head rod and the second connecting rod, and be connected and fixed by nut, the upper end of the 3rd connecting rod has and the identical hole of through hole on head rod, the 3rd connecting rod utilizes screw to pass the mounting hole of the second connecting rod lower end, by nut, be fixed, the lower end of the 3rd connecting rod is fixed on lower face shield.
Finally, described lower face shield and upper face shield are connected by screw and form a case, and follower is arranged in case.
Described lower face shield middle part has an axle, is arranged with the second iron cover on this axle, and follower is located at rotationally the second iron by the second bearing and puts.
Compared with prior art, the invention has the advantages that: because stay cord is not with pearl, in drawing process, with the contacting without impact of driving wheel, thereby silent, reaches quiet object, also easy and flexible more owing to not having the phenomenon of card bead to make to reel; Profile of tooth on driving wheel has directionality, and the tooth of rolling is more than the tooth putting down, facilitate casement roll and put down smooth and easy; Making traditional sprocket wheel into driving wheel can also be cost-saving, convenient processing; The two ends of the second connecting rod have mounting hole, can will between head rod, the second connecting rod, the 3rd connecting rod, carry out telescopic adjustment by connector, and then regulate the degree of tightness of stay cord; Simple to operate, more practical, especially in public places or recreating facility more suitable.
